Rise on Big Day
For SmallCap 600

Small stocks jumped, helping the Standard & Poor's SmallCap 600 index achieve its highest ever close and top the record levels it hit less than two weeks ago.

Still, small biotechs fell after large-cap Charles River Laboratories International lowered its forecast for full-year 2005 earnings. Cell Therapeutics fell four cents, or 1.7%, to $2.36, and InterMune fell 25 cents, or 1.5%, to 16.39.
